The average American who gets paid time off only uses about half of it, while 15 percent don’t use any at all. Additionally, workers end up leaving an average of three vacation days unused each year, the survey found.

Not surprisingly, women, minorities, and those with lower incomes are less likely to take vacation days.

“The lower the income of Americans, the fewer vacation days they have taken this year, while richer Americans have taken more,” the Skift reports. Around half of those in the bottom three income groups say they haven’t taken a day off, while just around a quarter of those making $75,000 to $149,000 say the same. No one making more than $150,000 said they’ve gone without a day off.

Men, too, are less likely to not take a vacation day, reportedly taking more than 10 days on average. More women, on the other hand, reported taking zero days off.

The blame of America’s workaholic syndrome is attributed to an entire culture of overworking for the reward of promotions and climbing the professional ladder.

“Less than a third say they’re encouraged to take their paid time benefits, while over a third of senior business leaders think those who take their allotted time are less dedicated, productive, and successful. Forty percent of workers say their ‘mountain of work’ makes it hard to take time away,” reports ThinkProgress.

Still, there are great benefits to taking time off. Not only is rest and relaxation good for your health, but it’s statistically proven to increase your productivity at work. Experts say time off gives you better life perspective and overall better well-being.
